Specicatipn of Letters Patent.

Patented Dec. 9, 1913.

Application led April 8, 1912. Serial No. 689,239.

To all lwiz/om t may concern.'

Be it known that I, WILLIAM CoYNE, a citizen of the United States, and a resident of the city of Kewanee, county of Henry, and State of Illinois, have invented certain new and useful Improvement-s in Pumps, of which the following is a specification.

My invention relates to improvements in pumps, and has for its object the provision of a pump of simple construction and eficient in operation. y

The invention consists in the combinations and arrangements of parts hereinafter described and claimed.

The invention will be best understood by reference to the accompanying drawings forming a part of this speciiication, and in whichv Figure 1 is a vertical longitudinal section of a pump embodying my invention, parts being shown in elevation, Fig. 2, a side elevation of the pump with parts shown in section, Fig. 3, a section taken on line of Fig. 2, Fig. 4, a bottom plan view of a casting employed in the pump, and Fig. 5, a bottom plan View of another casting employed in the pump.

The preferred form of construction, as illustrated in the drawings, comprises axially alining cylinders 1 and 2 consisting, respectively, of pipe sections 3 and 4, as indicated. The adjacent ends of cylinders 1 and 2 are formed by castings 5 and 6 seated on the ends of pipe sections 3 and 4 and separated by another pipe section 7 arranged between them and seated thereon.

`'lhe lower end of cylinder 2 is formed by a casting 8- seated on the lower end ofl pipe section 4 and the upper end of cylinder 1 is formed by a casting 9 seated on the. upper end of pipe section 3. Said parts are t'nmlybound together by means of tie rods 10 arranged as shown and having nuts 11 on theirends and bearing against the outer sides of castings Sand 9. Castings 5 and 6 'are provided with ports 12 and 13 leading into the ends of the correspondingv cylinders 1 and 2, respectively. A downwardly extending intake pipe 14 and an upwardly extending discnarge pipe 15 are connected with each of the ports 12 and 13, as shown, and each of said pipes is upwardly opening check valve 16. lntake pipes 14 areconnected at their bottoms with a" common intake pipe .17, and discharge provided with an pipes 15 are extended upwardly where they may be provided with any suitable means for utilizing water discharged therefrom. Alternately operating pistons 18 and 19 are arranged in cylinders 1 and 2 and are connected together by means of a common piston rod 20. Piston rod 2O passes through castings 5 and 6 where it is provided with suitable packings and a spring 21 is interposed between said packings in order to keep them tight. By this arrangement it will be observed that upon reciprocation of pistons 18 and 19, water, in communication with pipe 17, will be drawn upwardly into cylinders 1 and 2 alternately and alternately expelled therefrom throughI discharge pipes 15, check valves 16 opening and closing to .cause such action, as will be readily understood by those skilled in the art.

Casting 8 is provided with a port 22 communicating with the lower end of cylinder 2 and an air pipe 23 leads from port 22 to -a port 24 in the bottom of valve casing 25, as shown. Casting 9 is provided with a port z26 communicating with the upper end of cylinder 1 and connected by means of a pipe v27 with a port 28 also located in the bottom of valve casing 25. An exhaust port 29 is arranged in the bottom of valve casing 25 'between ports 24 and 28, as shown, and a slide valve 30 having a recess 31 in its bot-- .tom adapted to place either of the ports 24 -.or 28 in communication with exhaust port 29, is seated upon the bottom of valve casing v25. Alining valve cylinders 32 and 33 are Qarranged in valve casing 25 above valve 30 and valve piston heads 34 and 35 are ar- Iranged to reciprocate in cylinders 32 and 33, 'as shown. Valve heads 34 and`35 are connected by a rod 36 which in turn is connected with valve'30 by means of a ypin 37. -A supply port 38 leads into the top of valve scasing 25 between piston heads 34 and 35 and a supply `pipe 39 connects with port 38. By this'arrangement it will be observed that :upon supplying compressed air through pipe 39 and upon properly operating piston valve 'heads 34 and 35, valve 30 will be caused t-o operate to admit compressed air to the outer ends of cylinders 1 and 2 alternately and to exhaust the air from said cylinders alternately, to cause reciprocations of the pistons in said cylinders. The arrangement is such that valve heads 34 and 35 fit snugly against with water,

32 and 33 at the end of each stroke, and in order to give free access of the air to said cylinders and provide sufficient effective piston surface, the valve heads 34 and 35 are provided with recesses 34 and 35 in their Another port 45 is arranged in the side of valve casing 41 and is connected by means of a pipe 46 with a lport 47 communicating with the-end of valve cylinder 33. An eX- haust port 48 is arranged between ports 42 and 45and is provided with a suitable eX- haust pipe 49. A slide valve 50 which is similar in all respects to'slide valve 30, is

seated upon the side of valve casing 41 and serves, upon reciprocation, to supplyA compressed air to cylinders 32 and 33 alternately and to exhaust air from said cylinders alternately, to cause reciprocation of valve heads 34' and 35 and consequently reciprocation of valve 30. A block 51 is slidably mounted upon a rod 52 which extends upwardly from piston 18 and is connected thereto to reciprocate therewith. Stops 53 and 54 are arranged on rod 52 above and below block 51 and are so positioned as to cause reciprocation of block 51 at the end of each stroke of the pistons 18 and 19. Block 51 is connected with valve 50, as indicated, so that 'reciprocations of said block cause corresponding reciprocations of said valve. A guard tube 55 is larranged over the upper end of rod 52 and is adaptedto protect'said rod and permit reciprocations thereof. By this arrangement it will be observed that at the end of each stroke of pistons 18 and 19 the valve 50 will be automatically shifted to operate valve heads 34 and 35 to exhaust-'the previously operative cylinder 1 or 2 and to supply compressed air to the other of said cylinders to cause continuous reciprocat-ions of said cylinders as 'lo-ng as discharge from pipes 15 is permitted. v

In use, the pumpis arranged vin the boti tom of a well with the end of' pipe 17 submerged and pipes 15 connected with the water system which it is desired to supply and compressed airis constantly supplied through pipe 39. In case discharge of water is permitted from pipes 15, pistons 18 and 19 willy be continuously reciprocated to continue suchl discharge from said pipes as explained above. When the. discharge from pipes 15 is discontinued, the water in said pipes and in any system with which they connect, being incompressible, will stop further action of pistons 18 and 19, but immediately upon further withdrawal of water from pipes 15, pistons 18- and 19 re-commence their operations. It willbe observed that valve heads 34 and 35 are positively vand instantly operated by means of the pressure supplied to the .pump and thus the' action of the pump isv rendered entirely automatic and controlled by the withdrawal of water from thel discharge pipes, and all danger of stopping of the pump isavoided. p

While I have illustrated and described the preferred fo-rm of construction for carrying my invention into effect, this is capable of variation and modification without departing from the spirit of the invention. I, therefore, do not wish to be limited to the exact details of construction set forth, but

desire to avail myself of such variations and modifications as come within the yscope of the appended claim.

' Having described my invention, what I claim as new and desire to secure by Letters Patent, is

In a device of the class described, two alined pumping cylinders each having a port in the outer end thereof, pistons in said cylinders, a source of compressed air supply, a piston valve arranged to control the admission and exhaust of said compressed airto and from said ports, aseco'nd valve arranged to control said `piston valve, said second valve operating in alinement with said pumping cylinders, a block connected with said second valve, a rod connected to said pistons and slidably extending through said block, and stops on said rod adapted to alternately engage said block forl operating said second named valve, substantially as described.

In testimony @hereof I have signed my name to this specication in the presence of two subscribing witnesses.l
